Use JACT at your own risk

Strategies

GDAX trading bot. Add your own buy/sell strategies or use the ones provided. A custom strategy need only export a function that returns SHORT, LONG and be put in the lib/strategies directory. Technical indicators are provided by technicalIndicators. Up-to-date historical data (past 350 periods) can be retreived with HistoricDataProvider.get() and used in indicator calculations.

Trading

JACT will always place limit orders on your side of the spread to avoid taker fees.

If your strategy signals LONG or SHORT, JACT will try to place an order at the current "best bid" for LONG and "best ask" for SHORT.

If a LONG order is canceled, JACT will continue placing best possible orders until the position is filled either partially or entirely.

if a SHORT order is canceled or partially filled, JACT will continue placing best possible orders until the current position is closed entirely.

Stop Loss

JACT will constantly monitor the current price and compare it against any open position. If the current price falls below the config.stop_loss percentage it will immediately place a market sell order (has taker fee)

Backtesting

JACT has a basic backtesting feature. The config for the backtest can be altered in backtest.config.json. You can test your strategy against historical data of the dates you provide in start_date & end_date. Additionally, if you provide a slippage value, the backtest will apply a random slippage percentage no greater than the percentage provided to ~50% of all buy orders. Although it's not entirely accurate, it adds some noise to simulate market chaos.
